Kernel panic - not syncing: VFS: Unable to mount root fs on

[SimonomiS]

Hmm, but I can't even get that far.

It gets to the boot promt, any booting command gives me the not syncing; VFS etc error, and for other commands it gives me "kernel image sudo (or whatever it I try) not found".

Sorry, I didn't realize you were unable to boot at all. That command I gave can only be used in konsole, after a successfull boot.

Ah ok. Is there any emergency command that can rewrite the HD? Or another program that can do that? (I read Grub somewhere in this thread). If I can get over this, I think I'll choose something other than Knoppix as a HD based Linux distro heh.

OK You are the man !!

Boot your PC and wait until you get the Grub Menu

Then Press E on the 1st Entry
Then use arrow down to select the faulty Entry
Then press E again
Use arrow to the left until you get to the faulty entry (### ) and replace it with ramd

Press ESC

Press B to boot and be happy !!

I've gotten that far, how do you save your settings once you've edited ### isk to ramdisk?

Ok, I have Adriane Knoppix 6 installed to my second SCSI drive. I got the same error when appending the Adriane to the /boot/grub/menu.lst which was already working for me.

This is the menu.lst generated by 0wn..

This is the /boot/grub/menu.lst generated by TeenPup Linux and with the 0wn generated entry for Adriane appended.

And highlighted.

This is the boot message I get when booting either variant...

"[ 0.499891] dca service started, version 1.4

First partition is Knoppix 5.1

Second is M$ Windoze 2000

Third is Puppy Linux.

/sda1 is Freespire

All of them boot OK.

SCHEISSE...

I declined to install grub... this last time...

and installed Grub from Puppy linux.

Didn't have the "quiet" option.

SCSI.

At the last part, hundreds of lines of error messages... finally it comes to that.

(hd2,0) is a SCSI drive.

If I recall correctly there's a cheat-code to force recognition of SCSI.

It listed available partitions to boot, but all on IDE.
